Both players suffered knee injuries last week—Worthy's being bad enough to necessitate removal from the field by a cart—and both injuries could mean the Packers are without their services this weekend.

Now, Nelson went back on the field in part because Jarrett Boykin went down and they needed him, so we know he could play Sunday—though whether he did further damage to his leg by doing so is a question.

Cobb's return—which he calls 50/50, though the team is more confident—mitigates losing Nelson. We've seen the offense function without him before and it works pretty well.

Worthy is a loss which might not seem big—his stats aren't exactly beautiful—but he had been improving and has been a bigger factor the last few games.

Neither is the end of the Packers' chances in this game. Neither will be the reason they lose if they happen to lose.

But it's been a season of bruises and bangs for the Packers, and it appears that if they are going to win the Super Bowl, they might have to do it on crutches.
